A very small Gothic church built in 1230 to house a thorn from Jesus's crown, it's considered one of the best expressions of Italian Gothic. It is so small that in 1800, it was moved from the Arno riverbank to a place some metres higher, one stone at time, to protect it from flooding. It's usually not open to the public.
Santa Maria della Spina is a small church in the Italian city of Pisa. The church, erected around 1230 in the Pisan Gothic style, and enlarged after 1325, was originally known as Santa Maria di Pontenovo for the newer bridge that existed nearby, collapsed in the 15th century, and was never rebuilt.

Two opposing town square, one at each end of Ponte di Mezzo (middle bridge), and are considered the centre of the city. From Piazza Garibaldi starts Borgo Stretto, an old street with lots of shops that, together with Corso Italia starting in the opposite direction from Piazza XX Settembre, create a pedestrian area (interrupted only by the bridge) that is considered the centre of the city. In Piazza XX Settembre you can find the Logge dei Banchi, a building created to host textile market in 1600, and the town hall, in the Palazzo del Comune.
Keith Haring mural. Keith Haring visited Pisa and fell in love with the town, so he decided to paint this amazing mural as a gift to Pisa. Though extremely large, it is easy to miss so look out for it; it is located between via Giuseppe Mazzini and via Massimo D'Azeglio just off Piazza Vittorio Emanuele II.
